目的观察湖沼型疫区“无血吸虫感染者学校”健康促进干预模式的现场推广应用效果。方法选择鄱阳湖区3所重疫区学校为现场,基线调查后采用“信息传播+行为参与+行为激励”的健康促进模式对学生进行干预,比较干预前后学生血防知识和态度、疫水接触频率及血吸虫感染率方面的变化。结果干预后1年,3所学校学生血防知识及格率分别由干预前的8.91%、15.12%、18.56%提高到97.32%、96.04%、98.82%;血防态度正确率分别由干预前的9.90%、15.43%、17.53%提高到98.21%、99.34%、97.65%。干预前3所学校目标人群疫水接触率分别为13.01%、17.00%、22.99%,血吸虫感染率分别为10.89%、6.48%、9.28%;干预后1～3年内未发现疫水接触者和血吸虫感染者。结论“无血吸虫感染者学校”健康促进模式可在湖沼型重疫区推广应用。
Objective To observe the effect of on-site popularization and application of interventional model of health promotion intervention in schools of lakes and swamps infected with schistosomiasis without schistosome infection. Methods Three schools in Poyang Lake area were selected as on-site. After baseline survey, students were intervened by using “health education mode of information dissemination + behavioral participation + behavioral stimulation”. The knowledge and attitudes of students before and after intervention were compared, Frequency and schistosome infection rate changes. Results One year after intervention, the prevalence of knowledge about blood-protection among the three schools was increased from 8.91%, 15.12% and 18.56% before intervention to 97.32%, 96.04% and 98.82% respectively. The accuracy of blood-prevention attitude was 9.90% 15.43%, 17.53% to 98.21%, 99.34%, 97.65%. Before the intervention, the contact water rates of the target population in the three schools were 13.01%, 17.00% and 22.99%, respectively, and the infection rates of schistosomiasis were 10.89%, 6.48% and 9.28% respectively. No contact with water and schistosomiasis were found within 1-3 years after intervention Infected. Conclusion “School of schistosomiasis infection ” health promotion model can be popularized and applied in the severe flooding area of lake marsh.
